Abstract: Due to the blurred camera video caused by dust and water mist in the production process of comprehensive working face, the collision detection of shearer and hydraulic support cannot be normalized through video, which limits the practicability of intelligent mining technology. Based on the high-precision geological model of the comprehensive working face, the adaptive mining system issues the planned mining height data of the shearer, combined with the mining height sensor data of the shearer and the height sensor data of the hydraulic support, and carries out collision detection and early warning of the shearer drum and hydraulic support in real time, and the shearer traction stops after the early warning is triggered, and the adaptive mining system pops up a video window that triggers the collision detection support, and the shearer continues to adapt to cut coal after the alarm is manually processed and eliminated. The results show that the method correlates the relative coordinates of the shearer and the hydraulic support of the comprehensive working face with the absolute coordinates of the geological model, and realizes the early warning based on the height sensor data of the hydraulic support of the comprehensive working face and the planned cutting data, which greatly improves the accuracy of collision detection and early warning of the shearer and the hydraulic support of the comprehensive working face.
